Where Are Things Going?

Hello! My story is as follows. I have been in a relationship for 7 months with a boy, things are going normally, but I notice some things that give cause for concern. Here are: 1. We have decided to live together since the fall, at the moment the apartment is furnished, we are not rented, but nevertheless he twice said the following after a scandal: "you have a goal, you want to build serious permits, for you things will lead to marriage. " First, I never mentioned anything like that. Together we decided to live together, but that's it. I'm not paranoid about talking about a mess and babies at the beginning of a relationship. 2. He pretends that I look too far into the future (again, I don't know how to draw such conclusions), but he talks about what we will do in 10 years and what apartment to buy next, because it is bigger. Contradict yourself. 3. We used to have a scandal that he wants to go out and another, he arranges a meeting with not by inviting her, he tells me, but he does not invite me to even hint at them. I said then categorically that I do not accept them to see each other, because if he does not invite me with them, then I think I have cause for concern, and I do not think that this serious relationship is the least respect for me. After 2 months he invited her for coffee again and he would even hide from me, but I accidentally found out. We had a big scandal that day. I decided that the only option was to issue an ultimatum. After all, he has a desire to see only her, she was very close to him I do not know what, I close relationship between man and woman I know how they end. I told him which is more important for you to choose or get out of my head. Still, he stayed with me, but I'm not sure if that will happen again. I decided to find out that he had seen her part again, I'm not a mother eagle lurking. In the end, tell me what these 3 things show - does he have a serious relationship, he claims that he looks at me seriously, and almost at the same time he tells me that he wants to see other people. He told me in plain text - if you want to go out with others. I don't think this relationship is built on trust.
